A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methoxyphenoxy)propyl]oxazole (378 mg), 4,5-diphenylimidazole (270 mg), anhydrous potassium carbonate (220 mg) and N,N-dimethylformamide (10 ml) was stirred at 100° C. for 12 hours. The reaction mixture was poured into water, the resulting solid precipitate was filtered and air-dried. Recrystallization of this solid from acetone-isopropyl ether gave 4-(4-chlorophenyl)-2-(4,5-diphenyl-1-imidazolyl)-5-[3-(2-methoxyphenoxy)propyl]oxazole as pale yellow prisms (220 mg, 46%). Melting point 118-119° C.
